TL;DR: In this paper, the authors investigated the kinetics of calcite dissolution in aqueous KCl-solutions far from equilibrium, between 1 and 62°C in the pH-range 2.7 to 8.4 have been investigated using a rotating disc apparatus.

TL;DR: In this article, the rate of dissolution of calcite in aqueous solutions can be conveniently discussed in terms of three pH regimes: low pH ( 5.5), high pH (5.5) and mixed kinetics (H+-independent) regimes.

TL;DR: In this paper, a rotating disc system was constructed to study calcite dissolution kinetics and it was shown that the stirring dependence of systems which are not hydrodynamically well-defined is variable and dependent on the shape of the reaction vessel.

TL;DR: In this article, the authors investigated the kinetics of calcite dissolution in solutions containing dissolved Ca2+ using a rotating disc apparatus, and determined the chemical rate constant for Carrara marble dissolution to ∼2·10−2 cm s−1.

TL;DR: In this article, the distribution of the major elements Cl −, Na +, Ca 2+, Mg 2+ and K + in postglacial black clays is caused by diffusion of these elements to the surface during the 300 yr. the sediments have been above sea-level.
